Test died: Error connecting to root@redcurrant-4.qa.suse.de: No route to host

Observation¶

We have issues in multiple scenarios in first boot when connecting to PowerVM (and also we found some ipmi job).
The first test that tries to run select_console('root-console'); fails.

In ppc64le PowerVM:

Acceptance criteria¶

• AC1: Significantly higher code coverage in https://app.codecov.io/gh/os-autoinst/os-autoinst/blob/master/consoles/sshXtermVt.pm
• AC2: The typo is gone, e.g. just everything removed :)

Suggestions¶

• We accept the hypothesis that the jobs just failed due to lower level network issues #108845 which already received a fix meanwhile so nothing to do for the immediate root cause
• We can improve though:
  • There is a typo to fix in the message "does not seems"
  • Do not continue after ssh connect fails
  • But be explicit about the root cause. The test finally aborts with "No route to host" so we should have access to that message. for example in https://github.com/os-autoinst/os-autoinst/blob/master/consoles/sshXtermVt.pm#L60 make sure that the error details (underlying error message in $! or $@) are used for a better error message
  • Make sure that we have unit test coverage with some mocking for this behaviour
